public class SqlSessionFactoryUtil {

    private static SqlSessionFactory sqlSessionFactory;

    static {
        try {
            String resource = "mybatis-config.xml";
            InputStream inputStream = Resources.getResourceAsStream(resource);
          sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    public static SqlSessionFactory getsqlSessionFactory(){
        return sqlSessionFactory;
    }
}

下面的方式开启了自动提交

package com.hh.mybatis.utlis;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;

import java.io.IOException;
import java.io.InputStream;

/**

public class SqlSessionUtils {

    public static SqlSession getSqlSession(){
        try {
            InputStream is = Resources.getResourceAsStream("mybatis-config.xml");
            SqlSessionFactoryBuilder builder = new SqlSessionFactoryBuilder();
            SqlSessionFactory build = builder.build(is);
            SqlSession sqlSession = build.openSession(true);
            return sqlSession;

        } catch (IOException e) {
            throw new RuntimeException(e);
        }
